rework apiv2 wait endpoint|binding

added the ability to wait on a condition (stopped, running, paused...) for a container.  if a condition is not provided, wait will default to the stopped condition which uses the original wait code paths.  if the condition is stopped, the container exit code will be returned.

also, correct a mux issue we discovered.
